SHUTTLE MAGAZINE FOR AUTOMATIC LOOMS.

Application filed April 24, 1926. Serial No. 104,273.

My invention relates to a magazine for an automatic loom, in which the shuttles are stored and from which the shuttles are fed to the shuttle box mounted on the slay. The object of the present invention is to provide, at the entrance of the magazine, a means for preventing any shuttle positioned with its side upturned from entering the magazine, whilst allowing all the correctly positioned shuttles to freely pass to the maga zine.

In the accompanying drawings, in which I have illustrated my invention by way of example, Fig. 1 is a front view of the shuttle magazine constructed according to this invention,

Fig. 2 is a top plan thereof,

Fig. 3 is a detail view, and

Fig. 4 is a side view thereof, Figs. 3 and 4 having been drawn to a larger scale.

According to the drawings, 1 is the shuttle magazine in which a number of shuttles are stored. Then the shuttle is to be changed, the shuttle which is at the bottom of the magazine is pushed forward by the shuttle ejecting rod (not shown in the drawings) into the shuttle box mounted on the slay. It is a well known fact that shuttles to be stored in the magazine must always be fed in the correct position, that is, with their sides upright. In practice, however, the shuttle is frequently thrown in with its side upturned as shown at A in Fig.- 4, due to the careless handling of the operator. If the shuttle in such an irregular position is fed to the shuttle box, obviously it would interfere with the operation of the loom. According to this invention the above-mentioned disadvantage is removed by the means hereinafter described, which is adapted to prevent any shuttle A placed-in an incorrect position from being fed into the maga-- zine, whilst allowing the entrance'of the correctly positioned shuttles A.

At the entrance of the shuttle magazine and on the rear wall thereof, there are provided acting levers 2 which are rockably mounted on pivots 3. The levers 2 are normally held projecting inwardly by means of helical springs 4 encircling the pivots 3, in such a manner that the distance between the projecting head of each acting lever 2 and the front wall of the magazine will be approximately'equal to the height of the shuttle A.

On the rear wall of the magazine, at a place below .and opposite the acting levers 2, there are provided check levers 6, each having a shoulder 5. Each check lever 6 is rockably mounted on a pivot 7 At its upper end, the check lever 6 is engaged by the lower end of the acting lever 2, in such a manner that the former is rocked inwardly and outwardly depending on the rocking motion of the latter and consequently, the shoulder 5 of the check lever 6 is normally held projected into the passage of shuttles in the magazine, and when the check lever 6 is rocked outwardly, the shoulder 5 will be moved out of the passage of the shuttles.

Theoperation of the invention is as follows :VVhen the shuttle A is correctly positioned in the magazine, the acting levers 2, being pushed outwardly by the entering shuttle, will turn the check levers 6 outwardly, whereby the shoulders 5 will be moved out of the passage of the shuttle, thus allowing the shuttle to freely pass the entrance of the magazine.

If, on the other hand, he shuttle has its side upturned, as shown at A in Fig. 4, the shuttle will not push against the acting levers 2, so that the shoulders 5 of the' check levers 6 will remain in their projected position, thus preventing the incorrectly positioned shuttle from entering the magazine. In that event, the operator should correct his fault. 1

What I claim is j 1. In a shuttle magazine,the combination of a movable acting lever, and a movable check lever iii-engagement with said acting lever, the said two levers being adapted to be moved in and out of the path of the shuttle and being so disposed that upon said acting lever being pushed outwardly by a correctly positioned shuttle, said check lever is automatically moved out of the path of the shuttle.

2. Ina shuttle magazine, the combination of an acting lever pivoted to one of the walls of the magazine at theentrance thereof, and a check lever pivoted below said acting lever in opposition thereto and in engagement therewith, and a means normally holding said levers projecting into the path Q Leoaaaa of the shuttle, said check lever being Shaped; Inent therewith, and a'ineans normally holdto prevent an incorrectly positioned shuttle ing said levers projecting into the path of wfrom entering the magazine. 1 the shuttle, said check lever being formed 3. In a shuttlemagazine, the combination With a shoulder adapted to prevent an in- 5 of an acting lever pivoted to one of the Walls correctly positioned shuttle from entering of the magazine at'the entrance thereof, the magazine. and a check lever pivoted below said acting. In testimony whereof I affixmy signature. lever in opposition thereto and in engage- KHCHIRO TOYODAQ
